Repeater Operation
3-5
3-2.2.11 RF ON/OFF
The RF ON/OFF button is both a status indicator and a control. The name on the button is the state
of RF paths in the repeater. When the button reads “RF On” then both RF paths are powered-up
and operational. When the button reads “RF Off” both RF paths are powered-down, making the
repeater non-operational. Also, when the RF paths in the repeater are turned-off the button will turn
red for emphasis.
3-2.2.12 Alarms
The Alarm button is both an indicator, telling the operator that an alarm has been detected in the
repeater by turning red, and a control that brings up a separate alarm window that displays all
possible alarms, when its pressed.
In the alarm window are three groupings of alarms. There are a group of five General Alarms and a
group of alarms for each RF path. When an alarm condition is detected, the alarm parameter on the
panel will turn red, and stay red as long as the alarm is present. With the exception of an Oscillation
alarm and a General Power Amp alarm, the repeater maintains operation as much as it is able.
When there is an oscillation alarm, the unit will automatically lower the gain of the unit. If the
oscillation occurs even at the lowest gain setting, then the unit will shut down. However, if an
oscillation alarm or Power Amp alarm occurs, the repeater automatically shuts down the RF chains
and ceases to function and the “RFon” button on the WJ Repeater Control will turn red and read
“RFoff.” Once this occurs, the only way to clear the alarm in the repeater is to click the “Clear
Alarms” button. After clearing, the unit will continue to shut down as long as the alarm is present.
The A/C alarm will only turn on if the WJ Battery Backup has been installed and activated,
indicating that the battery backup is powering the unit since there is an A/C Power failure.
3-2.2.13 Multiple Repeater Interface
The Multiple Repeater Interface (MRI) is a unit that allows a user to communicate over a modem
with up to six repeaters over the same modem connection. When this application detects the
presence of a MRI unit, the MRI button on the main window is enabled. Pressing the MRI button
